Firebrick is a type of brick specifically designed to withstand high temperatures, making it ideal for use in kilns, fireplaces, and furnaces. It is made from refractory ceramic materials that can endure extreme heat without breaking down or losing structural integrity. Firebricks are often used in industrial applications, as well as in residential settings for wood-burning stoves and outdoor fire pits. These bricks come in various shapes and sizes, allowing for versatile construction options. Firebrick is typically classified into two categories: dense firebrick, which is strong and durable, and insulating firebrick, which is lighter and provides better thermal insulation.
